  • the draining member 30 is configured such that the film-like airflow N spouting from both sides of the pass line L is blown to corresponding portions on both sides of the sheet glass.
  • the slit 34 extends in the longitudinal direction of the intake pipe 33. It is formed continuously along the line or intermittently at small intervals. In any case, a continuous film-like high-pressure airflow N is continuously blown on the sheet glass G in the vertical direction (slightly inclined to the upstream side). This airflow is injected at a speed close to the speed of sound. This airflow is called air knife N.
  • the air supply pipe 33 is configured to rotate around its longitudinal center axis. As a result, the direction of the air knife N is changed. For example, it can be oriented perpendicular to the surface of the glass sheet, and then upstream and downstream. In addition, since the air supply pipe 33 is inclined slightly upstream from the vertical, the air knife N is turned slightly toward the upstream by rotating the air supply pipe 33, so that the air knife N becomes the surface of the plate glass. Water can be blown off slightly downward toward the upstream. As a result, the water is blown downward from the air knife frame 33 to the upstream side, and the water does not move to the downstream side. Moisture and the like are removed from the entire surface of the glass sheet that has passed through the air knife N, and the glass sheet is dried.
  • the washing members 28 and 29 are inclined slightly upstream from the vertical, fresh water is supplied from the top to the top of the sheet glass that is being conveyed, and high-quality washing is possible. It becomes. Further, like the air supply pipe 33, the flush members 28 and 29 are also configured to rotate around the central axis in the longitudinal direction. As a result, the injection direction of pure water is changed.
  • separators 35 are provided adjacent to the drainers 30 on both sides of the pass line L.
  • the separator 35 is for preventing water from moving from the drainer 30 to the downstream side.
  • Each separator 35 protrudes outward from the drainer 30 in a direction perpendicular to the vertical plane (substantially the glass surface) including the pass line L.
  • the separator 35 is inclined from the vertical direction to the upstream side in parallel with the air supply pipe 33 and the washing members 28 and 29. It has been extended. As a result, no matter how much the water jetted on the upstream side jumps, it is prevented by the separator 35 from moving toward the draining member 30 on the downstream side.
  • the separator 35 may be provided, for example, close to the downstream side of the downstream washing member 29.
  • the fluid guide 27 uses pure water as a supporting fluid upstream of the separator 35, and uses ultra-clean air as a supporting fluid downstream of the separator 35. Therefore, no water is used downstream from the air knife frame 33 and the glass sheet is dried.
  • the belt conveyor 2 which is a supporting device in each of the devices 3, 4, 5, and 6 of the cleaning equipment 1, can be moved to drop the supported glass sheet downward.
  • the gap between the fluid guide and the plate glass is constant due to the surface tension of the supporting liquid. It becomes a thick liquid layer and can be transported while supporting the glass sheet in a state of non-contact with the structure.
  • a liquid as a guide fluid, it is possible to more effectively remove force-ret particles and other dust from the sheet glass.
  • a sheet glass is exemplified as a processing target, but the present invention is not limited to a sheet glass.
